Ok so what does this mean....
1. the four corner pins are connected to 5v
2. the 2 middle pins on each side of the chip are connect to ground
3. the pins on the outside of the ground pins are connect to the motor
4. the pins on the outside of the motor pins are connected to the inputs.
I have verified those contacts with a multimeter and they are all getting there respective connections and voltages.
So it is connect correctly.
But when the input pins are driven, one high and one low, the motor doesnt move. I used my multimeter to show that they are being driven high/low. But when i check the outputs, i find that they are not getting voltage. I have tried 2 l293d and i am sure they cant both be not working. What is the problem.
int out1 =3;
int out2 =4;
